FAQ
Q: Can I use a robot vacuum on stairs?
A: No. Robot vacuums cannot navigate stairs. You need a handheld or stick vacuum for stair cleaning.
Q: What attachment is best for carpeted stairs?
A: A motorized mini brush head is ideal. It agitates carpet fibers to lift embedded dirt and pet hair.
Q: How often should I vacuum stairs?
A: At least once per week, or more often in high-traffic areas or homes with pets.

The Dyson V12 Detect Slim is our top pick for stairs — light enough to carry, powerful enough to deep clean. The Shark Wandvac is a great budget alternative for quick cleanups.
